I never would have thought of washing them with soap, seems so weird to me. Just use a dish soap, like dawn? If I got water to a boil and put them in for a minute would that be ok as well?
I'm just new to buying peppers and have been really into them, but don't think I have really cleaned them before I ate them. Just a rinse under hot water in a strainer and then cooked them. I guess cooking them would kill bacteria, but with hot peppers that I might want to just eat raw I would need to clean them.
And by sterilizing them, I'm talking about killing anything on them that might be harmful to ingest.
